Re: a conundrum, maybe? feed a baited swarm but not disturb it?!
Mitch, the little swarm I caught Sunday was brushed into a five frame nuc with drawn comb. Bees were still arriving so I was unable to put the inner cover on which holds the mason jar feeders I use. I just set a jar directly on the frames and covered it with a medium box. I left the top slightly open so bees could continue to enter the hive. (Robber screen is permanatly attached.) The next day I put the inner cover on the bottom deep and refilled the EMPTY jar of syrup, placing it on the screened opening in the inner cover.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
